Optimal power flow using Teaching-Learning-Based Optimization technique

•We solved the optimal power flow for different cases.•We used a new technique which is the Teaching-Learning-Based Optimization (TLBO) Technique.•Compared to other techniques the TLOB is highly effective in solving the optimal power flow.•The efficiency of the TLBO has been proven by carrying out a statistical analysis.•Unlike other optimization techniques TLBO has no internal parameter to tune.

Teaching-Learning-Based Optimization is a rising star among metaheuristic techniques with highly competitive performances. This technique is based on the influence of a teacher on learners. In this paper, the Teaching-Learning-Based Optimization technique is used to solve the optimal power flow problem. In order to show the effectiveness of the proposed method, it has been applied to the standard IEEE 30-bus and IEEE 118-bus test systems for different objectives that reflect the performances of the power system. Furthermore, the obtained results using the proposed technique have been compared to those obtained using other techniques reported in the literature. The obtained results and the comparison with other techniques indicate that the Teaching-Learning-Based Optimization technique provides effective and robust high-quality solution when solving the optimal power flow problem with different complexities.
